Richmond Hill Resources PLC: Sakoose Drilling Underway - First Hole Completed

FRANKFURT, Germany, Nov. 11, 2026 /PRNewswire/ -- Richmond Hill Resources PLC (AIM: RHR, Frankfurt: V39), a gold exploration company focused on the Martello Gold Project near Dryden in north-western Ontario, Canada, announces that drilling is underway at the historic Sakoose gold mine.

The first hole has been completed and the second has commenced as part of the planned nine-hole, approximately 1,400-metre diamond drilling programme.

The programme has two objectives: to confirm the high-grade gold reported by earlier operators and test extensions of the vein system; and to establish whether gold in the surrounding host rock adds width to the vein intersections.

Highlights

• First drill hole completed, with the second hole commenced.
• Nine holes planned for approximately 1,400 metres, combining tests close to historical gold intersections with exploration of interpreted extensions.
• Expanded systematic sampling across three planned holes will test surrounding host rocks alongside the principal veins, assessing the potential for broader gold-bearing zones.
• Sakoose forms part of the Company's 100%-owned, approximately 6,750-hectare Martello Gold Project.
• Geological logging and sample selection are underway. No assay results from the current programme are available yet.
